❔ Pinging hundred of hosts sequentially

Ping pingSender = new Ping();
PingOptions options = new PingOptions(128, false);
for (int i = 0; i < data.Count; i++)
{
    var sessRes = data[i];
    var reply = pingSender.Send(sessRes.HostAddress, 1000, filler, options);
    if (reply.Status == IPStatus.Success)
        sessRes.Ping = (uint)reply.RoundtripTime;
    Thread.Sleep(100);
